The outlet of a solar collector is connected with the air suction inlet of an inverter compressor, the air outlet of the inverter compressor is connected with the inlet of a tube heat exchanger, the outlet of the tube heat exchanger is connected with the inlet of an expansion valve, the outlet of the expansion valve is connected with the inlet of the solar collector, the water circulating outlet of a heat storage water tank is connected with the tube heat exchanger after passing through a water pump, the outlet of the tube heat exchanger is connected with the water circulating inlet of the heat storage water tank, another path is connected with a floor heating coil pipe through the heat storage water tank to provide heat, and backwater is discharged into the heat storage water tank through a circulating water pump. The invention has the advantages that the system performance is high, and has a wide applied area.

Description

technical field [0001] The invention relates to a heating system in the technical field of solar energy, which is a building-integrated solar heat pump heating system based on adaptive control. Background technique [0002] As a sustainable green and clean energy, solar energy is considered to be the most promising energy that human beings can look forward to after the 21st century, and has received widespread attention from the international community. Solar energy is the main source of all energy on the earth. The annual solar radiant energy reaching the earth's surface is 5.57×1018MJ, which is equivalent to 190 trillion tons of standard coal, which is about 1.56×104 times the current total primary energy consumption in the world. Compared with the limited age of human development history, solar energy can be said to be an "inexhaustible and inexhaustible" energy source. my country's solar energy resources are also very rich, mainly concentrated in Tibet, Qinghai, Xinjian...

Problems solved by technology

Its shortcoming is that the variable frequency compressor adopts fixed frequency, which cannot be adjusted with the change of external environmental parameters, and if the change of environmental parameters exceeds the design working condition of the fixed frequency variable frequency compressor, the energy consumption of the system will increase rapidly with the frequency of system operation , which leads to a significant decrease in system efficiency (including heat collection efficiency and COP, etc.) when the external working conditions change significantly; in addition, the hot water produced by the original literature system does not consider the integration of energy-saving buildings, resulting in practical Sex is not high
